fix(compat): Bereinigung liegengebliebener Prüf-Einträge löschte laufende Prüfungen

Entwürfe haben in WordPress kein gültiges GMT-Datum (0000-00-00), deshalb hielt die Orphan-Bereinigung jeden markierten Prüf-Eintrag für alt und konnte eine laufende Divi-Prüfung abbrechen. Der neue Kern-Baustein ThrowawayPost setzt beim Anlegen ein echtes GMT-Datum, prüft das Alter über post_modified_gmt und kapselt Anlegen, Prüfen und Löschen (Anlegen jetzt innerhalb von try). WriteProbe nutzt ihn; Fehlermeldungen von WordPress gehen nur noch ins Error-Log. Live in DDEV belegt: frischer Eintrag bleibt, 11 Minuten alter wird gelöscht.
